What struck me most about this SPACE.com article by Andrea Thompson was the speculation on what this "missing matter" really is.
"Using Hubble's Space Telescope Imaging Spectrograph (STIS) and NASA's Far
Ultraviolet Spectroscopic Explorer (FUSE), the astronomers found the
spectral 'fingerprints' of highly ionized hydrogen and oxygen, thought to form
the IGM [intergalactic medium].
'We think we are seeing the strands of a web-like structure that forms the
backbone of the universe,' said study team member Mike Shull. 'What we are
confirming in detail is that intergalactic space, which intuitively might seem
to be empty, is in fact the reservoir for most of the normal, baryonic matter in
the universe.'""He had read of 'Space': at the back of his thinking for years had lurked
the dismal fancy of the black, cold vacuity, the utter deadness, which was
supposed to separate the worlds. He had not known how much it affected him
till now--now that the very name 'Space' seemed a blasphemous libel for this
empyrean ocean of radiance in which they swam. He could not call it 'dead';
he felt life pouring into him from it every moment....He had thought it
barren: he saw now that it was the womb of the worlds....No: Space was the
wrong name. Older thinkers had been wiser when they named it simply the
heavens--the heavens which declared the glory [of God]...."
